Antisolvent-Enhanced Crystallization of Luminescent All-Green Organic-Inorganic Manganese-Halide Films Deposited by Aerosol-Assisted Chemical Vapor Deposition Technique on Either Glass or Elastomer Substrates

The in situ deposition of emerging organic-inorganic metal halides (OIMHs) films on glass or stretchable substrates has been challenging, and no methodology has been reported to achieve this goal. The aerosol-assisted chemical vapor deposition technique using an antisolvent-enhanced crystallization process (AEC-AACVD) is a simple, cost-effective, scalable, and high-throughput technique operated under ambient atmosphere and pressure. The AEC-AACVD technique (an all-green chemistry methodology) is used in this work to deposit TPA2MnCl2Br2 luminescent films on glass and highly stretchable elastomer substrates. The effect of using different antisolvents on the structural, morphological, and photoluminescent (PL) characteristics of films deposited on glass is reported. It is found that the intensity of the characteristic green emission peaks at 511 nm for this OIMH, improving with the antisolvent application. The TPA2MnCl2Br2 films deposited using a mixture of antisolvents result in the maximum emission intensity when deposited on stretchable substrates, maintaining their overall PL characteristics. The processability, scalability, and performance reported here for these films prove their potential application in the next generation of OIMH-based optoelectronic technologies. TPA2MnCl2Br2 films with intense green photoluminescence (PL) centered at 510 nm are deposited on glass and stretchable elastomer substrates, using an antisolvent enhanced crystallization in aerosol-assisted chemical vapor deposition method. The structural, morphological, and PL properties of the films improve with the use of different antisolvents, and the most intense PL is obtained using a mixture of antisolvents.image (c) 2023 WILEY-VCH GmbH
